tDamesProductions Posted March 9, 2011 Report Share Posted March 9, 2011 Hey, I'm kinda new to the site and not new to audio but it stomps me when i get to the Ohm part. I have American Bass XO's and I want to bridge them but everytime I do it cancels itself out and comes in and out. The way I have it wired is positive on both sides of one sub (and negative) and I have them together and They lead out to 1 positive and 1 negative as a normal speaker of course and same with the other.

C-Fizzy Posted March 9, 2011 Report Share Posted March 9, 2011 Wait what, you can't bridge subs. You either have them wired in series or parallel.

RichyMitch925 Posted March 9, 2011 Report Share Posted March 9, 2011 i think your parallel so your at 2 ohms Quote Owwwwwwwwww Link to comment Share on other sites More sharing options...
Cashdollar2009 Posted March 9, 2011 Report Share Posted March 9, 2011 That's a parallel wiring configuration, giving you a nominal load of 2-ohms. When you say "bridge," that is just a certain way to wire your subwoofer stage to your amplifier, it has nothing to do directly with your wiring configuration. BUT, as a guess, your amplifier is only 4-ohm stable bridged, so when you wire down to 2-ohms, your amplifier is cutting in and out of protect trying to prevent you from frying anything... :/ Quote 1997 Chevrolet Cavalier Two 12" DC Audio XL M2'sCrescendo Audio BC5500d Current Scores: 150+ out the Trunk On 6/30/2011 at 1:11 AM, 'Ray' said: Acoustical energy is free.

Guest Posted March 9, 2011 Report Share Posted March 9, 2011 are you trying to run the subs in parallel AND bridge the amp? because no wonder it went into protect, because each channel is seeing 1 ohm and the lowest it can handle is 2 ohms (in stereo, 4 ohms bridged).
